10:50 Invited talk: Laser scanners with rotational Risley prisms: A graphical method to determine and study exact scan patterns
Virgil-Florin Duma (1), Alexandru-Lucian Dimb (2)
(1)Aurel Vlaicu University of Arad (Romania) , (2)Polytechnic University of Timisoara (Romania)
We report on a novel, graphical method, using a 3D mechanical design program, CATIA V5R20, to obtain and analyze exact scan patterns or a pair of rotational Risley prisms - in comparison to other scanning modalities, produced by the most common galvanometer laser scanners.

11:10 Invited talk: Integrated microresonator frequency comb source for massive-parallel optical communication

We demonstrated ultra-dense wavelength-division multiplexing (WDM) data transmission using an intensity modulation and direct detection (IM-DD) scheme. We discuss the feasibility of SiN and MgF2 microresonators for WDM applications regarding output power, bandwidth, and required pumping power. In addition, we discuss that IM-DD communication is relevant to the next-generation optical communication that requires ultra-low latency.

In this talk I will introduce the barium titanate photonics platform. The Pockels effect is what enables GHz-level switching speeds in optical modulators and switches, so materials which exhibit strong Pockels coefficients are advantageous as they maximize light-matter interaction. Using pulse laser deposition, we have grown single crystal barium titanate on various low index substrates and measured an r-parameter over 600 pm/V. We then experimentally demonstrated polarization modulation.

We present photonics-enabled technologies to realize high-speed fiber-wireless-fiber bridge systems in the millimeter-wave band, including a photonics-enabled receiver and an all-photonic receiver. In the former method, the millimeter-wave signal is down-converted to the microwave band before being converted to the optical signal for further transmission using an optically generated local oscillator signal. In the latter method, the millimeter-wave signal is directly converted to the optical domain without any frequency conversion using a broadband optical modulator.

In this talk, we review recent advances in robust optical data processing using silicon PICs: 1) On-chip reconfigurable optical full-field manipulation for grooming photonic signal processor (reconfigurable optical add/drop multiplexer, filter), 2) On-chip mesh-structure-enabled programmable multi-task photonic signal processor (filter, delay, router, switch), 3) On-chip multi-dimensional (mode, polarization, wavelength) selective switch, 4) On-chip intelligent mode switching in fiber-chip-fiber communication systems.
